Ordered the Hellwig 7216 and 7217 kits for front and rear sway bars from SD Truck Springs for $863.00, this included and additional $40.00 off deal. It took 2 hours to do the front bar replacement. The rear bar is in addition to the OE sway bar. The hardest part was the frame brackets and getting clearance with the leaf springs in the way. Ended up using the MH jack system to unload the suspension a bit to gain access. Took us 4 hours to do the rear. Getting the new longer shackles bolts (8 of them) torqued to 300 ft-lbs was entertaining.

Big improvement in stability... no more wobbly box. Easy 2 finger driving down the road. Glad I did it.

Has anyone added rear swaybar on 390 rb I have a 2014 that I have added roadmaster steering stablizer but would like to do something to the rear

I have added both a rear track bar and a front steering stabilizer to my 2015 Georgetown 364TS. There was about a 30 percent improvement, but not what I was looking for. Interestingly, I just came back from TX four days ago. After a flat tire (slow leak in valve stem) I crawled under the coach and found that the rear sway bar had broken loose from its mounting bracket on the differential. The Ford Motorhome Division directed me to a nearby (53 miles) dealer who works on motorhomes. As I was describing the problem to the Service Manager he said "does it look like this one on my desk?" Although he doesn't know why they break, he's seen it before. In my continuing attempt to handle the excessive sway, I am going to the Hellwig...first the front and then the rear if the front alone isn't enough. So far, I'm into this thing $1,800 with little improvement.

Sorry took so long to get back been working on shed. Sounds like maybe need to wait and see if that's works for you before sending a bunch of money. Seems to me this is a problem alot of people have, I say fix before leaving factor would do best.

Through all of this, the FR tech rep was with me to ensure Ford did what they needed to do. When the sway bar bracket was done, the FR tech rep asked if there was anything else he could do for me. I said, "Yes, in fact there is something else you can do for me. Given the sway problems I am having, and in light of the $1,800 I've already spent, what might FR recommend to solve this problem?" I'm looking forward to their response and will share it with the others.

ChckSix, I am right on the verge of buying the Hellwigs but want to hear from FR first, which I suspect will be in the next day or two. Where did you purchase your Hellwigs? What do you think if I were to purchase just the fronts first to see if they might solve the problem?

I purchased them online at SD Truck Springs. Re-read my first post in this thread for the details.

We already discussed earlier in this thread doing front only and my opinion is, don't mess around. Buy both front and rear Hellwigs and install them. It took me and my buddy 6 hrs to do it and you do have to have some serious tools. I've mentioned some of them earlier, like the torque multiplier. I ended up doing both for under $1000.00 + my labor. If you pay someone else to install them, plan on 6 hrs of shop labor x their shop hourly rate.

The Ford OE hardware is Mickey Mouse stuff compared to the Hellwig parts.

If you do order from SD Truck Springs, be advised they have the bars and hardware kits drop shipped from Hellwig directly to the buyer. In my case, it took a tick over 2 weeks from order, to delivery.

Hey checksix.
I ordered the 7216 rear kit also but it didn't come with any instructions at all. Did you get any? Can you share?
Got it from sdtruckspring also.
